यदि \(A=\{1,2,3\}\) और \(B=\{0\}\) है तो (A) से (B) में कितने फलन बनेंगे?
If \(A=\{1,2,3\}\) and \(B=\{0\}\), how many functions are possible from (A) to (B)?
Explanation opens after your attempt
A. (1)
Concept
For each domain element, (B) has only one choice (0). Hence the total number of functions is \(1^3=1\).
Why this answer is correct
The correct answer is A. (1). For each domain element, (B) has only one choice (0). Hence the total number of functions is \(1^3=1\).
Exam Tip
हर प्रांत तत्व के लिए (B) में केवल (0) एक ही विकल्प है। इसलिए कुल फलन \(1^3=1\) है।
